the mail bag or other article cannot be opened without unfastening thepad-lock or cutting the cord.

The primary function of the deviceherein disclosed is to hold the endsof a cord together, securely, so that the ends of'the cord may beretained by a pad-lock or the like.

The invention aims to provide a device of this type in which a pair ofcooperating parts are so constructed as to prevent an unwinding of thecord from one part. I

A further object of the invention is to provide, upon one of the parts,means for preventing the cord from being slid endwise off the otherpart.

WVith the foregoing and other objects in view, which will appear as thedescription proceeds, the invention resides in thecombination andarrangement of parts and in the details ofconstruction hereinafterdescribed and claimed, it being. understood that changes in the preciseembodiment of invention herein disclosed can be made within the scope ofwhat is claimed without departing from the spirit of the invention.

In the drawings,Figure 1 shows the invention in perspective applied to amailbag; Fig. 2 is a. transverse section of the device; Fig. 3 is alongitudinal section thereof; Fig. 4 is a perspective of the cap; andFig. 5 is a perspective of the base.

The invention includes, as constituent parts, a base 1 and a cap 2, thebase and the cap preferably being of rectangular contour.

Projecting from one of the constituent parts of the structure,preferably from the base 1, is a lock holder, in the form of an eye 3,the eye 3 being adapted to pass through an opening 4 in the cap 2. Thecap 2 is provided along certain of its edges with proj ecting,oppositely disposed flanges 5, adapted to overlap the edges 6 of thebase 1, the flanges 5 being spaced from the edges'6 of Specification ofLetters Patent.

the base 1, as indicated at 7 toprovide for ,the insertio-n of the cord,as will be set forth hereinafter. The base 1 is supplied along others ofits edges, with projecting, oppositely disposed flanges 8, adapted tooverlap the edges 9 of the. cap 2. The flanges 8 of the base 1 areterminally extended, as shown at 10, to overlap the ends 11 of theflanges 5 of the cap 2. Upon the inner face of the base 1 there arespaced ribs 12, extended at right'angles to the flanges 8, and upon theinner faces of the flanges 8 there are ribs 1a, located approximatelyparallel to the base 1.- Extended longitudinally of the cap 2, upon theunder face thereof, are spaced ribs 15. r

In practical operation, a cord 16 is assembled with the mail bag orother article 17, in the usual manner, the ends of the cord being woundabout the base 1, parallel to the flanges 8, any desired number ofconvolutions being passed about the base 1. The cap 2 is then superposedupon the base 1, the eye 3 passing through the opening 4., a lock 18 orother fastening means being extended through the projecting portion ofthe eye, as indicated in Fig. 1.

tend across the ends of the cap 2, the convolutions of the cord 16 whichsurround the base 1 cannot be slid endwise off the base, therebypermitting an opening of the mail bag 17. Owing to the fact that theflanges 5'of the cap 2 overlap the side faces 6 of the base 1,'it willbe impossible to secure a straight pull upon the cord 16, whereby thecord may be withdrawn from between the base 1 and the cap 2. Since theends of the flanges 8 of the base 1 overlap the end faces 11 of theflanges 5 of the cap 2, it will be impossible to insert a wire or thelike with in the cap 2, parallel to the flanges 5, for the purpose ofdisplacing any of the conv0-' lutions of the cord 16 wherewith the base1 is surrounded. The ribs 11 upon the flanges 8 obviously aid inpreventing a displacement of the cord 16 from the base 1. The ribs 15 ofthe cap 2 cooperate with the ribs 12 of the cap '2, "and thus a seriesof kinks are formed in the cord 16, preventing Owing to thefact that theflanges f the base 1 eX- an endwise withdrawal of the cord. The

ribs--15 of the cap 2 lie upon opposite sides of the opening 4', and thecap is thus reinforced, to offset the weakening incident to theformationof the opening 1,

Having thus described the i11Vention,What is claimed is 1. A device ofthe class described comprising as constituent parts, a base and a cap,one of which parts is provided with an eye, the other of which parts isprovided with an opening to receive the eye, the cap having projectingflanges along certain of its opposite edges, overlapping certain of theedges of the base but spaced therefrom to provide for the passage of acord, the base having projecting flanges along others of its oppositeedges, overlapping other edges of the cap, the flanges of the base beingterminally extended beyond the base to overlap the ends of the flangesof the cap, there being cord-holding ribs upon the adjacent faces ofsaid constituent parts, the ribs of one part being located upon oppositesides of the opening therein, to offset the weakening of said partresulting from the formation of the opening.

2. A device of the class described comprising as constituent parts, abase and a cap, one of which parts is provided with an eye, the other ofWhich parts is provided With an opening to receive the eye, the caphaving projecting flanges along certain of its opposite edges,overlapping certain of the edges of the base but spaced therefrom toprovide for the passage of a cord, the base having projecting flangesalong others of its opposite edges, overlapping other edges of the cap,the flanges of the base being terminally extended beyond the base tooverlap the ends of the flanges of the cap.

In testimony that I claim the foregoing as my own, I have hereto affixedmy signature in the presence of tWo witnesses.
